More scared off on delays then prices. 
Ironically I'm not even seeing Southwest as an option for me. Seeing some Delta and United for cheaper options. And more Delta flights with no layovers so will probably go that route.
Southwest hasn't been an option for me in a while. Some years ago, yes. They were cheaper then. Now, I'm not seeing much of a price difference. Maybe for shorter hops, but from the east coast, they're not looking cheaper. And add to that (for me), the very few non stop flights. Granted, I do look, but my expectations at finding what I want from them is low, so I'm not really disappointed when I don't find anything. I've been leaning toward United for the most part, although I will take a peak at Delta as well.
